Special Issue Information

Dear Colleagues,

Sustainable agriculture and the restoration of agroecosystems affected by climate changes are critical concerns for global agriculture. Intensive agricultural practices and exploitation of agricultural lands have emerged as the key threats to the future of agriculture. Thus, sustainable agriculture strategies, such as diversifying crops, implementing agroforestry, using green methods to treat agro-food waste, and using conservation tillage, aim to improve soil fertility, preserve water, and decrease reliance on chemical inputs. This ultimately reduces the environmental impact of farming. Furthermore, the agroecosystem was negatively impacted by global climate change. Restoration initiatives prioritize the rehabilitation of degraded areas by implementing reforestation, wetland restoration, and sustainable management practices for ecosystems and biodiversity. These measures effectively restore altered biodiversity and ecosystem services. These strategies not only reduce the negative impacts of climate change via carbon sequestration and improving resistance to severe weather conditions but also enhance the well-being of farmers by fostering more reliable and efficient agricultural systems. Combining traditional knowledge with cutting-edge technologies provides a comprehensive approach to promoting sustainable and climate-resilient agrarian ecosystems.

This Special Issue aims to collate both original research and review papers reporting on the sustainable management of soil fertility, biochar and carbon sequestration, green remediation of environmental pollutants, sustainable recycling of agro-food wastes, groundwater restoration, and the restoration of changing environments affected by climate change. Additionally, advanced, eco-friendly, biotechnological approaches to sustainable agriculture are highly encouraged. In summary, this Special Issue will update our understanding concerning soil restoration, sustainable management of abiotic stress through environmentally friendly techniques, and agro-food waste recycling.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Nutrient use efficiency and water use efficiency;
  • Sustainable and green remediation of pollutants in agriculture;
  • Sustainable management of agricultural waste and waste valorization;
  • Conservation agriculture and soil restoration;
  • Recycling of agro-food waste and circular economy;
  • Biochar for soil conditioning and green remediation;
  • Management of soil salinity and drought through advanced technology.

We hope to hear from you soon.

It is well known that environmental factors, management strategy, and genotype can affect the composition of maize seeds. For this reason, eight maize conventional varieties from Korea were grown over three years, 2021, 2022, and 2023, in three sites, Daegu, Hongcheon, and Suwon of South Korea, to describe the natural variation in the maize seed composition. The results indicate a sizable variation in component contents such as proximate, minerals, and fatty acid among the various varieties, which was more pronounced at the Daegu and Suwon cultivation sites and varieties. Since the DO3, JDO, and KIO are the dominant varieties, showing significantly higher accumulation of proximate (14.3%, 15.2%, and 13.1%), minerals (13.1%, 16.6%, and 14.7%), amino acids (17.01%, 15.1%, and 13.5%), and fatty acids (14.3%, 13.9%, and 15.1%) components, when comparing the genotype effects on seed composition. On the other hand, a significantly higher level of seed components, such as proximate (37.2%, 33.4%), minerals (38.5%, 33.4%), amino acid (38.3%, 33.1%), and fatty acids (36.5%, 33.9%), were found in the maize seeds grown in Daegu and Suwon when compared to Hongcheon. This may be possible due to the soil geochemical properties of Daegu and Suwon. Moreover, the comparison of cultivation years did not show a significant contribution to seed composition; however, a slight or moderate difference was found between the year 2023 and the years 2021 and 2022 of cultivation. An analysis of variability percentage and a principal component analysis showed that the compositions of maize seeds were influenced by genotype, location, and the interplay between genotype and location. In conclusion, compositional diversity in maize was influenced by the interaction between genotype, location, and environment. Full article

Globally, cadmium (Cd) stress dramatically reduces agricultural yield. Illite, a natural clay mineral, is a low-cost, environmentally acceptable, new promising method of reducing the heavy metal (HM) stress of cereal crops. In research statistics, there is little research on stress tolerance behavior of Illite (IL) on an experimental soybean plant. In the present study, we took IL and examined it for tolerance to Cd, as well as for other plant-growth-promoting (PGP) characteristics in Glycine max (soybean). The results showed that applying clay minerals in different concentrations enhanced the level of SA (defense hormone) and reduced the level of ABA (stress hormone). Cd 1 mM significantly reduces plant growth by altering their morphological characteristics. However, the application of IL significantly enhanced the seedling characteristics, such as root length (RL), 29.6%, shoot length (SL), 14.5%, shoot fresh biomass (SFW), 10.8%, and root fresh biomass (RFB), 6.4%, in comparison with the negative control group. Interestingly, IL 1% also enhanced the chlorophyll content (C.C), 15.5%, and relative water content (RWC), 12.5%, in all treated plants. Moreover, it resulted in an increase in the amount of superoxide dismutase (SOD), phenolics, and flavonoids in soybean plants, while lowering the levels of peroxidase (POD) and H2O2. Furthermore, compared to control plants, soybean plants treated with the Illite exhibited increased Si absorption and lower Cd levels, according to inductively coupled plasma mass spectrometry (ICP-MS). Thus, the IL can operate as an environmentally beneficial biofertilizer and sustainable approach under Cd stress by promoting plant development by activating signaling events. Full article

High salinity poses a significant threat to arable land globally and contributes to desertification. Growth-promoting rhizobacteria assist plants in mitigating abiotic stresses and enhancing crop productivity through the production of siderophores, exopolysaccharides (EPS), solubilisation of phosphate, indole-3-acetic acid (IAA), and other secondary metabolites. This study aimed to isolate, identify, and characterise bacteria that exhibit robust growth-promoting properties. A total of 64 bacterial isolates from the rhizosphere of Miscanthus sinensis were evaluated for plant growth-promoting (PGP) traits, including IAA, EPS, siderophores, and solubilisation of phosphate. Among them, five isolates were selected as plant growth-promoting rhizobacteria (PGPR) based on their PGP features and identified via 16S rRNA sequencing: Enterococcus mundtii strain INJ1 (OR122486), Lysinibacillus fusiformis strain INJ2 (OR122488), Lysinibacillus sphaericus strain MIIA20 (OR122490), Pseudomonas qingdaonensis strain BD1 (OR122487), and Pseudomonas qingdaonensis strain MIA20 (OR122489), all documented in NCBI GenBank. BD1 demonstrated a higher production of superoxide dismutase (SOD) (17.93 U/mg mL), catalase (CAT) (91.17 U/mg mL), and glutathione (GSH) (0.18 U/mg mL), along with higher concentrations of IAA (31.69 µg/mL) and salicylic acid (SA) (14.08 ng/mL). These isolates also produced significant quantities of amino and organic acids. BD1 exhibited superior PGP traits compared to other isolates. Furthermore, the NaCl tolerance of these bacterial isolates was assessed by measuring their growth at concentrations ranging from 0 to 200 mM at 8-h intervals. Optical density (OD) measurements indicated that BD1 and INJ2 displayed significant tolerance to salt stress. The utilisation of these isolates, which enhances plant growth and PGP traits under salt stress, may improve plant development under saline conditions. Full article

Pesticides are inevitable agrochemicals employed as plant protection agents and their application follows good agricultural practice (GAP). Although pesticides are primarily used for plant protection purposes, the residual pesticides may pose a threat to the next crops and/or off-target biota. Another important aspect of applied pesticides is the transformation into toxic metabolites. As a result, misuse or overuse of pesticides can lead to raised residual uncertainty, hidden risk of transformed metabolites, and potential risk to off-target biota. As per pesticide safety guidelines, regulations for the maximum limit of residual pesticides, addressing toxic metabolites derived from parent pesticides, and managing the potential risk of pesticides for off-targets are considered vital components. Despite the countable number of studies that have already been published on pesticide fate, residual risk, and metabolism in soils and plants, several vital research gaps remain untouched. In this study, the vital research gap of pesticide fate and transport is explored through vital keyword searches, followed by sorting of relevant articles using scholarly search engines. According to the study outcomes, residual uncertainty, secondary pollution, diversified fate and transport, and toxic metabolites, including their persistence, were detected as key research pitfalls. Thus, this paper critically addresses the current trends and research gaps and suggests specific recommendations for pesticide fate and potential risk studies. Full article
